TECH NOTES

  This is the Futaba GY401 Gyro with an S9254 Digital Servo.  This is a high performance, compact and lightweight  (AVCS) Angular Vector Control System gyro developed for model helicopters.  Because the sensor and control circuit are integrated, it is simple to install.    FEATURES: AVCS System: Since the rudder trim changes (caused by wind and other  meteorological changes) the front, rear, and other heli attitudes  change and are automatically cancelled; tail (rudder) operation is  easy, making it perfect for 3D flight.  (also known as heading hold gyro)  SMM Gyro Sensor: Use of this newly developed technology virtually  eliminates rudder trim changes during flight (see COMMENTS).  Digital Servo Compatible (DS Mode): DS mode makes it compatible with  Futaba Digital Servos. This maximizes the high-speed response  performance of the Digital Servo.  Included high-speed S9254 Digital Servo boasts 47 oz-in torque and a  speed of .06 sec/60°  Remote Gain Function and Mode Switching Function Remote: Gain  function allows sensitivity switching from the transmitter and mode  switching function allows AVCS/normal gyro mode switching.  Integrated, compact and lightweight design made possible by high  density mounting technology.  Conductive Resin Case: This case improves EMC (Electrostatic and  electromagnetic interference) resistance.

The new SMM (Silicon Micro Machine) technology is the integration  of mechanical elements, sensors, actuators and electronics all  brought together on a common substrate chip. This hobby industry  first, results in a gyro sensor with an unprecedented level of  functionality, reliability, and sophistication.  This will not work with JR Digital servos. These have a different  pulse.  Voltage- use only with a 4.8V battery. (if you use it with a  higher voltage battery it needs to be regulated to 6V)
